ConfigurationRuleIfBranch Object Preview

Derived from: Base Object
Defined in namespace "adsk::fusion" and the header file is <Fusion/ConfigurationRules/ConfigurationRuleIfBranch.h>

PreviewThis functionality is provided as a preview of intended future API capabilities. You are encouraged to use it and report any problems or suggestions using the Fusion API and Scripts forum.

Because this is a preview of future functionality, there is the possibility that it will change, which will possibly break any existing programs that use this functionality. Because of that, you should never deliver any programs that use any preview capabilities. For a distributed program, you should wait until it has moved from preview to released state.

Description

One branch inside an If block's elseIfBranches list. Each branch carries its own condition and a list of then-statements. The branch is evaluated only if the parent If's primary condition and all preceding elseIfBranches' conditions are false.

Methods

Name Description
classType

Static function that all classes support that returns the type of the class as a string. The returned string matches the string returned by the objectType property. For example if you have a reference to an object and you want to check if it's a SketchLine you can use myObject.objectType == fusion.SketchLine.classType().

create

Creates a new, detached IfBranch with no condition and no then-statements.

Properties

Name Description
condition Gets and sets the condition evaluated to decide whether this branch's then-statements run. Null when no condition has been set.
isValid Indicates if this object is still valid, i.e. hasn't been deleted or some other action done to invalidate the reference.
objectType This property is supported by all objects in the API and returns a string that contains the full name (namespace::objecttype) describing the type of the object.

It's often useful to use this in combination with the classType method to see if an object is a certain type. For example: if obj.objectType == adsk.core.Point3D.classType():
thenBlocks Gets and sets the statements executed when this branch's condition is true.
